A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Dec 01, 2014· Sieve Analysis (ASTM C 136, AASHTO T-27): This test method evaluates the gradation of aggregate using a series of sieves. The results are then plotted on to a semi-log aggregate gradation chart. This chart shows the particle size distribution for any given aggregate and can then be better evaluated for its use in portland cement concrete and,

In this study, variations in the free radical concentration, degree of swelling (Q), and extraction yield of Buertai coal (C%, 80.4%) in 11 solvents with different characteristics were determined to investigate the interaction between the coal and solvent, as well as the bond cleavage during solvent extraction. Derivative thermogravimetry (DTG) results for the residues and raw coal

Lignite means a type of coal classified as lignite A or lignite B by the American Society of Testing and Materials in ASTM D388 (incorporated by reference, see § 60.17). Low heat release rate means a heat release rate of 730,000 J/sec-m 3 (70,000 Btu/hr-ft 3) or less.

When you can deduct an expense depends on your accounting method. An accounting method is a set of rules used to determine when and how income and expenses are reported. The two basic methods are the cash method and the accrual method. Whichever method you choose must clearly reflect income. For more information on accounting methods, see Pub. 538.
